The main object of this invention is to provide a guard carriage movable in an elevator shaft which is retained in lifted position above the custodian of a dwelling, and receives such objects as falling milk bottles or the like from an upper floor, thereby preventing the person, who may at that moment be removing ashes or other refuse,.from being struck in the dumbwaiter well.

Another object of the invention is to provide a guard carriage which is movably mounted on rails in a dumbwaiter shaft and serves as a guard for a person in the shaft beneath the device. The above and other objects will become apparent in the description below in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Figure 1 is a longitudinal elevationalview of a dumbwaiter shaft showing the guard carriage mounted in place therein. 3

Figure 2 is a cross sectional view through the .dumbwaiter shaft showing the guard carriage in place therein.

Figure 3 is a perspective view of the guard carriage.

Referring in detail to the drawings, the numerals 10 and 12 indicate the side walls of a dumbwaiter well. These side walls are joined by a rear wall 11 and front wall 13,

and form an enclosure in which dumbwaiter' 31 is lifted to different floor heights. Rising vertically and mounted upon one of the side walls 10 are a pair of spaced apart stationary guide rails 14.and 15 in which channels 15a are formed. These channels extend the entire length of the rails 14 and 15. These rails 14 and 15 serve as a support for movable carriage which is guided along these rails in a vertical path. The carriage comprises a plurality of straps 16, 17, 18 and 19 which are formed into a square and have ledges thereon, upon which rests a rubber or felt cushion 32. Mounted upon this rectangular carriage carriage is to prevent injury to a person reis a frame member comprising uprights 23' and 24 and cross bars 20. The cross bars have carriage. At one or more positions on the carriage, hooks 26 are mounted. These hooks have one end of a cable 29 secured thereto. Said cable has a weight 30 fixed to its opposite end, and is trained about pulleys 27 and 28, in order to permit the weight at the end of the cable to lift said carriage adjacent to 6 i said guide rails. The area is of skeleton construction and its area 33 is covered by a mesh work, comprising cross slats 34 which are secured to springs 35, the opposite ends of said springs being fixed to the frame work of the carriage.

The device is adapted to be installed in an elevator shaft and rests above the opening in an elevator well, so that-a person may remove refuse and the like therefrom. When it is desired to lower the elevator 31 to a position i where access may be had to it from the lower portion of the well, the guard carriage is lowered manually. The object of the guard moving refuse or the like from a dumbwaiter '75 well to be struck by falling missiles, such as milk bottles or the like. The slats 34 being connected to the springs 35, which are in turn secured to the frame of the guard carriage are yieldable and therefore will not fracture such delicate and brittle objects as glass bottles.

It is to be noted that certain changesin form and construction may be made without departing from the spirit and scope of the invention.

I claim: 1

In a vertical elevator having I-rails provided with opposing channels, a guard carriage comprising a skeleton frame, said frame {Q0 having an aperture, a resilient lattice work covering said aperture including springs, guides integral with said frame registering slidably in the channels of said rails, said guides comprising ledges entering into said channels, a Weight suspended from a pulley, and a rope passing around said pulley and being secured to said carriage, the latticed members of said aperture covering having their ends secured to the springs, the springs being secured to said frame.

In testimony whereof I afiix my signature. ANDREAS LANG.
